SHOE WELT Original Filed Sept, 26, 1927 In venaf.- /fw V, 3y, 704W, @www ornc Patented Jan. 12, 1932 PATENT OFFICE JOHN V. MATTOS, OF TAUNTON, MASSACHUSETTS SHGE WELT l Original application led September 26, 1927, Serial No. 221,902. Divided and this application filed January 17, 1930.

The invention relates to a new and useful improvement in shoes and it relates especially'to the welt. The present application is a division of my application Serial No. 221,9027

Y i filed September 26, 1927.

The invention will be fully understood from the following description when taken in connection with the accompanying drawings and the novel features thereof| will be pointed out and clearly defined in the claim at the close of this specification.

In the drawings:

Fig. 1 is a longitudinal section of one form of shoe having incorporated therein a welt embodying the invention.

- Fig. 2 is a perspective view of a portion of a'welt embodying the invention before it has been folded and incorporated in the shoe.

Fig. 3 is a longitudinal section of an insole which forms part of the shoe with which the welt is used.

Fig. 4 is a fragmentary plan view of the completed shoe.

Referring to the drawings, there is shown at 10 the upper of a slice, at 11 the insole, at 12 the filler, at 13 the outer sole, and at 14 the welt. Preferably the body of the insole 11 is made of sheet cork, although it may be made of any suitable material and is enclosed in a casing comprising a top and edge covering 15 and a bottom covering portion 16, both of said coverings being of any suitable iexi ble material. The upper covering portion 15 extends over the edge of the insole and partly around 'on the underside and is there turned to form a lip portion 15a. The bottom covering portion 16 meets the upper portion 15 somewhat inside of the margin of the insole and is turned to form a lip 16a, the said two lip portions 15a and 16a facing each other as shown in Figs. 1 and 2 to form a two-ply lip f to receive the stitches 17 for uniting the VYupper, the inner sole and the welt.

The welt 14 is formed with a longitudinal groove 18 in one face thereof to facilitate the folding of the welt as will be hereinafter Vdescribed and is also formed with a longitudinal groove 19 to form a channel for the stitches.

The covering members 15 and 16 for the Serial No. 421,398.

insole are cemented thereto and are pounded down and the lip portions 15a and 16a have their contiguous portions cemented together. The lip f extends substantially at right angles to the underside of the insole.

In the process of making the shoe, the insole is temporarily secured to the bottom of the last by tacks, after which the upper 10 is put on the last and the shoe islasted in the usual manner and the welt 14 is stitched to the upper 10 and to the lip f of the insole. The welt is sewed to the insole and the upper by the stitches 17 before the welt is folded and the upper is trimmed close to the welt. The filler 12 is then applied to the under face of the insole 11 within the recess bordered by the lip f and is secured to the insole preferably by cement-ing it to the covering 16 on the under side of the insole.

The welt 14 is then folded along the line of the groove 18 so that the fold is on the outer or exposed edge as shown in Fig. 1, thus making a two-ply welt, the two plies being in contact with each other. Prefer'- ably the two plies of the folded welt are cemented together as shown at 6 in Fig. 1. The welt is then beaten by a beating-out machine and the outer surface is sand papered after the welt is folded.

The outer sole 13 is then applied over the cork filler 12 and is sewed to the welt 14 by stitches 21 which pass through the sole and both folds of the welt 14 as clearly shown in Fig. 1.

The outer sole is then trimmed close to the folded edge of the welt.

What I claim is:

A shoe welt consisting of a strip of flexible material formed with two parallel longitudinal grooves in one face thereof, said welt being folded along the line of one of said grooves, the other groove forming a channel which receives stitches for uniting the welt to the insole and upper.

In testimony whereof I ai'lix my signature.

JOHN V. MATTOS.
